I've got a clip of black chipper low on my insta (my profile's private so can't link it here, but will message you on there).
Regardless, I used a right heel on the lip of the slab and had my LF down left and out of the way. I also started cross handed on the flake, but that doesn't make much difference.
Getting into position before pulling on is surprisingly awkward, which does make it a bit rubbish really, but the rest is good enough.
